That seems to be entirely the prevalent case in between making the injectors perform like factory ones do. There is no amount of support on their end which will get that set up for you.


It takes a lot of time and effort to get it right. Probably more than most are willing to put in, but with that precise level of control of them you're more likely to wind up with much more precise fueling across the entire RPM band spectrum, this winds up showing up in the fuel trim stability throughout.
There was literally 20+ tables that needed to be changed vs LT4 ones lol and I’m sure that was one of them. LPE reviewed my tune (their injectors, made by Nostrum) and couldn’t find anything wrong. I then reached out to Nostrum multiple times and couldn’t get a single reply. If I decide to dig back into this, I’ll connect up with you if you don’t mind.
